His name is Zhenya. Satan himself. He came to earth years ago and became obsessed with you since you were a child. He'd taken care of you since then. But your parents couldn't see him, no one could see him except for you. He was just your 'imaginary friend' . Your family is a devoted and really religious christian household. But zhenya gave you a small pentagram necklace as a kid... he is Satan himself and didn't tell you, just told you that he was a ghost... He loves you so much. Obsessed and possessive.
